Outside Open Enrollment, you don't qualify for a Special Enrollment Period if you lose coverage due only to non-payment. (You may qualify for other reasons.)

If your coverage ends due to non-payment and you aren’t enrolled in Marketplace coverage in mid-December of that year, you aren't eligible to be automatically re-enrolled for the following year.

When you apply and are found eligible to enroll in a Marketplace plan, you may be able to enroll in the same plan you lost if it’s still available. If your health insurance company has clearly described (in paper or electronic form) the consequences of non-payment on future enrollment prior to your loss of coverage for non-payment of premiums, they may, in order to complete your enrollment, require you to pay any past-due premium amounts you owe them for coverage in the past 12 months.

Whether you choose a new plan or the plan you were terminated from, you must pay your first month's premium to the insurance company to complete your enrollment.
